Yield measurements for the 11B(p,n)11C and the 10B(d,n)11C nuclear reactions.
The yields from the 11B(p,n)11C nuclear reactions have been measured over the energy range of 0-28.6 MeV. The yields from the 10B(d,n)11C nuclear reactions have been measured over the energy range of 0-21.5 MeV. Cross-section values were derived from the yield data. The yield measurements were carried out on sealed samples of boron powder isotopically enriched to greater than 93%. The target holders were constructed of aluminum and each contained 50 mg of boron powder to achieve high energy resolution, but with sufficient material to ensure accurate cross-section measurements. 11C yields were determined by decay-curve analysis. Our data show that at energies below 5 MeV, the 11B(p,n)11C nuclear reaction can be expected to produce 250 mCi of 11C (based on a 30 min irradiation at a beam current of 100 microA).
